Application led October 1,

To all whom t may concern.' v

Be it known that I, HERMAN HANSON, a citizen of the United States,`residing at Garfield,V in the county of Douglas and State of Minnesota,have invented certain new and useful Improvements' in lVeeders andPulverizers7 of which the following is a specification. v

This invention relates to a weeder and pulverizer attachment forcultivators and has for its principal objectto provide a device of thisnature which will be efficient and reliable in operation and will bereadily placed in and out of engagement with. the ground when sodesired.

Another object of the invention is to provide simple and efficient meansfor attaching the device to a cultivator ofl conventional construction,said attaching means being -adjustable so as to accommodate the variousdifferences found in conventional cultivators.

With these and numerous other objects in view the invention comprisescertain novel features of construction and the arrangement andcombination of parts aswill be hereinafter more fully described andclaimed.

In the drawings Figure 1 is aY plan view of the device showing the sameattached to a portion 0f a cultivator;

- Figure 2 is a fragmentary side elevation ofY the rear portion of thedevice;

Figure 3 is a longitudinal vertical section taken through the device;and,

Figure 4 is an enlarged section taken on the line 4-4 of Figure 1`looking in the direction of the'arrow.

Referring to the drawing in detail it will be seen that 1 designates acultivator of conventional construction which is usually provided withthe rear diverging arms `2 and as isi well known the angle formed bythese diverging arms 2 varies considerable inva` rious cultivators nowcommonly in use and it is the purpose7 therefore, of the presentinvention to provide an attachment which' is capable of being secured topractically all conventional cultivators having a portion somewhatsimilar to that illustrated to advantage in Figure 1.

This attachment consists of the beam 3 having fixed thereto a vpluralityof curved fingers 4 each of which is provided with a shank 5 bent inL-shape so as to t over the top of the beam 3 andk along the forwardside thereof. These Shanks are held in Speccaton'of Letters; Patent.Pafentedeuine 27',

place by means of eye bolts 6l which pass i through the beam- 3.U-shaped rod 7 i is fixed to each end of the beam 3 by having one legthereof rivetedto the terminals of the beam as shown at 8 and the otherleg 9 projecting a short .distance into the beam if .n

so desired.YY A coil 'spring 10 is disposed on theA rod 7 and has foriits fpurposeto noi`` provided with a longitudinally extending slot 13and an eye 14 for yreceiving the rod 1 7. Theleaf 13 :is provided atVits terminal with a suitable eye which is in engagement p with an' eye17 carried on a brace rod 18. The other end of the brace rod 18 isprovided Vwith an aperture for receiving the bolt 19 which passedthrough the slot 13 and thus the angle between the leaves 12 .and 13 maybe varied to accommodate the angle of the diverging arms 2. It willfurthermore be seen that the attaching means is adjustablelongitudinally of the beam 3 since the spring 10 maybe compressed forthis purpose.

the Vdepending arm22 is attached to a coil spring 23 which is also`attached to a bar; 24 or any `,other suitable part of the culti-v vator1 for the purpose of normally holding the fingers in engagement with theground.

A flexible member 25 is povided with a snap f hook 26 at its'end and issuitably attached to the upstanding arm21'whereby this `flexible membermay be pulled toward' the cultivator so as to rotate the beam therebylifting the fingers 4 outV of engagement with the ground at' the sametime expanding thercoil spring 23 and the snap hook 26 may be placed inengagement with any portionof the Vcultivator so as to keep thev fingers4 out of engagement with the ground as long as desired. ,f

. e5 l By having the rods 7 passing through From the foregoingdescription taken in connection with the accompanying drawing, theconstruction and the operation of the attachment will be readilyunderstoodwithout more extensive explanation. As numerous changes inform, proportion and the minor details of construction may bel resortedto without departurev from the spirit of this invention, l do notwish tolimit the construction herein shown and described other than as claimed.

Having thus described my invention what I claim as new is:-

1 .In combination, a cultivator provided with rearwardly extendingdiverging arms, an attachment therefor consisting of a beam,

U-shaped rods secured to the ends of the beam, springs mounted on therods, attaching means pivotally mounted on the rods and including a pairof hinged leaves one of which being provided with a slot, means forattaching the other leaf rigidly to the arms of the harrow, a brace rodpivotally mounted on the last mentioned leaf, and a bolt passing throughthe vslot of the other leafV
